the reports speak of people roaming the streets and shooting randomly even at fronts of buildings just to keep any protesters from coming outside. residents reached by phone claim these people are foreign mercenaries in gadhafi's pay. gadhafi's regime is splitting. the u.n. ambassador actually encouraged the protesters to keep going to saying that if they stop now, they would lose, they had to keep going. gadhafi himself made a bizarre 22 second appearance. he's opened the door of a car, held up an umbrella, said he wanted to join pro government demonstrator, but it was raining thanks to god and now he was going away, but he was not leaving libya. that's sort of the kind of thing he doesn't usually do. he makes these rambling long speeches. so we don't know where he is or what he's doing, betty. >> gadhafi has vowed that he will not step down, but his regime is falling apart, so how long can he hang on and if he does flee, where will he go?

same mistakes as his predecessors as he tries to tackle the $3.6 billion shortfall. union members say they will make concessions like greater contributions to hair health and pension plans. but they won't give up their voice in collective bargaining. >> busting up my union is not going to solve any budget problems. it's not about that. it's about a power play here. >> reporter: while the governor was speaking, outside his heavily guarded press conference, thousands of protesters jammed the capitol hallways chanting for his resignation. >> even if it bill passes, we won't be going away until we get our rights back. >> reporter: the governor could hear the demonstrators but appeared unfazed by the week long proper tests. >> you can hear them out will, they're here each and every day and they have every right to be heard. >> reporter: and he has a message for the 14 democrat senators avoiding the vote. >> time for them to come back and participate in democracy. >> reporter: the legislature goes back in session tuesday, but democrats say they won't

on the on the "cbs morning news," here's a look at today's weather. in the northwest, expect rain and snow showers. temperatures are feeling cooler throughout the northeast and northern plains. and the southeast is staying warm and toasty. here's another look at this morning's top stories. at least 65 people were killed when a powerful earthquake hit new zealand. the quake struck about midday new zealand time and centered near the city of christchurch. at least eight large buildings collapsed trapping hundreds. and the libyan military and security forces have launched a deadly crackdown on anti-government protesters. the violence has prompted numerous government officials to call for moammar gadhafi's resignation. on a lighter note, a

nonalcoholic beer is being touted as a healthy sports drink. a european brewer is now promoting erdinger beer for athletes. it's vitamin rich, has no additives and can help an athlete recover. unlike gatorade, it has a golden color and is frothy like beer. it sells for about ten bucks a six pack. meanwhile obesity is a growing health crisis. more than 70 million adults are considered obese. in 2009, 220,000 people turned to gastric bypass and lap band operations to lose weight. jennifer ashton reports. >> reporter: after considering all the options for weight loss surgery, 46-year-old tracy brosnan chose lap band and she's lost 82 pounds in two years. >> i was looking for a tool to help me. and i found it with the lap band. >> reporter: tracy may have beaten the odds, but a new study out today says lap band is not as effective as gastric bypass surgery.

during bypass, a small stomach pouch is created with staples. a loop of smalls intestine is attached to the pouch so food bypasses part of the intestines and is only partially absorbed. with a lap band, an adjustable band is placed around the upper portion of the stomach which limits the quantity of food consumed. bypass patients lost an average of 97 pounds compared to 55 pounds in the lap band group. a second study looking at diabetes reduction compared gastric bypass to a procedure called sleeve gastrectomy. the stomach is made smaller holding less food. the excess stomach is removed. again, gastric bypass was superior. diabetes disappeared in 93% of gastric bypass patients compared to 47% of sleeve gastrectomy patients. all of these procedures cost between $15,000 and $30,000, but those costs are actually far less than a lifetime of treating diabetes and its complications. i'm dr. jennifer ashton, cbs news, new york. good information there. well, this morning on "the early
